Application led April 27, 1925. Serial No. 26,099.

T0 aZZ 1.071.071@ t may concern Be it known that I, HENRY E. DURTSCHE, acitizen of the United States, residing'at Galion, in the county ofCrawford and State of Ohio, have invented a certain new and usefulImprovementv in a Gauge, of which the following is a full, clear, andexact flescription, reference being had to the accompanying drawings. I

This invention relates to a gauge which is designedk especially for usein connection with the inspection of dimensions and clearances onlocomotives, such as ladderrungsI` hand rails, hand grabs, steps,uncoupling levers and so on. rIhe inspection of such parts is usuallydirected toward the determination of minimum clearance and thicknessrequired to insure safety.

It is an object of the present invention to provide a one-piece gaugewhich is so shaped that the desired minimum limits are delined byportions thereof compactly arranged and readily accessible. In thisconnection my invention contemplates the provision of a gauge havingsuitable recesses, the walls of which provid-e 'different limitingdimensions, whereby I obtain a large number of limiting dimensions upona comparatively small gauge.

I carry out the above objects by employing a substantially rectangularpiece of metal and having indentations on the sides, and having alateral extension adjacent one side. These indentations have oppositelyfacing tongues which enable the diameter of a. mei ber to be readilydetermined. Moreover, I so form the gauge that each corner embodies aright angle, wherefore the overall length of the sides may be used forlimit measurements. In this way I provide a single gauge which may bereadily used for example in measuring all the locomotive clearancescovered by prescribe-d minimum safety requirements, for example from{1G- inch to 4 inches.

My invention is shown in the accompanying` drawings, wherein Fig. l is afront elevation of the gauge; Fig. 2 is a plan view taken along thebottom edge of the gauge, and Fig. 3 is a rear elevation of the gauge.

rlhe gauge embodying my invention has a body portion l0 and a laterallyextending portion 1l which is integral therewith. The bottom and sidesofthe body portion are shown as being serratedand as having opposedtongues to provide different outside diameter limits, while the sidesand top have differentV overall limits.

The outside diameter limits are indicated at 12. 13, 14 and 15 asdefining limits of fg, 5/8, .1/2 and 778 respectively.v The body portionadjacent each of said outside diameter limits has a recess which mayconveniently be semi-circular. The depth of this recessis somewhat morethan half the distance between the gauge points so thata round bar mayenter the recess lsufficiently tok bring the diameter of the bar wellbetween the gauge faces. I find it convenient for example, to make therecess for the 7/8 gauge of 1/2 radius struck from a center along theline connecting the inner edges of the gauge faces.` Similarly therecess for the 5/8 gauge may be of 3/8 radius and so on.

The side 20 in addition to the limiting tongues 13 has limiting tongues2l which may be used for ldetermining the minimum thickness of a member.The limits defined by the tongues 2l are indicated in Fig. l as one andone-half inches. The outermost limit of the side 20 is shown in Fig. 3as defining two and one-half inches. i

Along one edge of the body portion I have indicated a shoulder 22providing an edge 23 having any overall limit of one inch. The remainingportion of the top edge of the body portion merges with the top edge ofthe lateral extension 1l so as to provide a. three inch gauge from theshoulder 22 to the outermost end 24 of the extension. The width of theextension is indicated in Fig. 3 as being 5/8, while the lower surface25 of the extension is shown as being 2 .in length.

In addition to the limits which are defined by the recessed portions, Iso form my gauge that the overall length of each side has aypredetermined limit. For example, the overall distance of the bottomedge 27 is two inches; that of the side 20 is shown as 21/2; thedistance between the side 2O and the end 24 is 4; while the side 28which extends from the bottom 27 to the extension 25 is 1%.

From the foregoing description, it will be evident that I have'provideda simple tool wherein a large number of limiting distances are providedon a comparatively small single-piece gauge. The use of a single gaugehaving the required predetermined limits enables an inspector to reducematerially the time for making an inspection.

' Having thus described my invention, I claim:

l. A gauge. having a body portion and having a lateral extensionintegral therewith and projecting from one edge of the body-i portion,said extension being provided With a scale, and the body portion havinga recess in one of its other edges to define an outside measurement.

2. A gauge comprising a single piece member havingabody portion and alaterally extendingy portion, each of said portions having the edgesthereof disposed at right angles to each other, one of the edges. on thebody portion being inalignment with one of the edges on the laterallyextending portions, said body portion having, recesses in differentedges thereof, there being oppositely facing tongues associated witheach recess to define a limiting distance, the limiting distance of eachrecessvbeing different from the limiting distances of the remainingrecesses.

3. A gauge. having a body portion and a laterall extending portion, thebody portion having each side arranged at right angles to the adjacentside, each of said sides having a recess therein, and a pair of inwardlyprojecting tongues associated with each recess to dene a limitingdistance, each of Which is different from the remaining limitingdistances, the respective sides having different overall limitingdistances.

4. A gauge comprising a one-piece member, having a body, portion and alaterally extendingfportion, the body portion having two rsides thereofparallel and having a third side arranged at right angles to theparallel sides, one ofthe parallel sides having. a plurality of recessestherein, each recess havinga pair of oppositely facing tongues, eachpair of tongues defining a limiting distance, the remaining sides of thebody portion also having a recess therein, and havinga pair of tonguesassociating with each recess to provide-other limiting distances, eachof said limiting` distances being different from the remainingdistances.

In testimony Where-of, l hereunto afiiX my si gn ature.

HENRY DURTSCHE.
